Safety Information
The following section contains important safety information that you must follow when installing and
using the hardware.
Do not operate the hardware in a manner not specified in this document and in the user documentation.
Misuse of the hardware can result in a hazard. You can compromise the safety protection if the hardware
is damaged in any way. If the hardware is damaged, return it to National Instruments for repair.
Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely dry and
free from contaminants before returning it to service.
Do not substitute parts or modify the hardware except as described in this document. Use the hardware
only with the chassis, modules, accessories, and cables specified in the installation instructions or
specifications. You must have all covers and filler panels installed during operation of the hardware.
Do not operate the hardware in an explosive atmosphere or where there may be flammable gases or
fumes unless the hardware is UL (U.S.) or Ex (EU) Certified and marked for hazardous locations. The
hardware must be in a suitably rated IP 54 minimum enclosure for hazardous locations.
You must insulate signal connections for the maximum voltage for which the hardware is rated. Do not
exceed the maximum ratings for the hardware. Do not install wiring while the hardware is live with
electrical signals. Do not remove or add connector blocks when power is connected to the system. Avoid
contact between your body and the connector block signal when hot swapping hardware. Remove power
from signal lines before connecting them to or disconnecting them from the hardware.
Caution The MID-7604/7602 does not provide overload protection for motor loads. Overload
protection must be provided externally by the system designer.
Caution The MID-7604/7602 does not provide motor overtemperature sensing. External
temperature sensing must be provided externally by the system designer. Temperature sensing is
required for monitoring the motor temperature and disabling the drive.
Caution The stepper motor connectors on this drive are energized when the unit is powered on.
Disconnect the MID-7604/7602 unit from the power outlet before connecting wires to or
disconnecting wires from the stepper connectors. Strip back the insulation of the stepper wires to the
stepper connectors no more than 7 mm.
Failure to do so could result in electric shock leading to
serious bodily injury or death.
Hot Surface The bottom surface of the MID-7604/7602 can get very hot to the touch under certain
conditions. To avoid a burn hazard, refer to Output Current Settings in the Front Panel DIP Switch
Settings section of this guide for the appropriate current setting and safety hazards.
